空分多路 meaning in Chinese

sdm space division multiplexing

Hc - sdma high capacity - spatial division multiple access hc - sdma
大容量-空分多路存取
Due to the data transmission characteristics between tags and reader , space division multiple access ( sdma ) , frequency division multiple access ( fdma ) and code division multiple access ( cdma ) are applied in a limited way in rfid system . therefore , time division multiple ( tdma ) has been generally accepted . according to tdma , there are aloha protocol , s - aloha , binary - tree protocol , clipped binary - tree protocol and others
解决这个问题必须要用到多路存取法，针对射频识别系统中阅读器与应答器之间的通信特点，空分多路法、频分多路法、码分多路法在rfid系统中应用都受到一定的限制，只能应用到一些特定的场合，一般采用时分多路法，按照时分多路法的算法有aloha算法、时隙aloha算法、二进制树型搜索算法、修剪枝的二进制树型搜索算法等防碰撞算法协议，分析了各自特点以及存在的缺点。
